' LIQUID-DISPENSING MACHINE.

1T 0 all whom it may concern:

' Be it known that I, CARLTON a citizen of the United States, residin at Houston, in the county of Harris and tate of Texas, have invented certain new and useful Improvements in Liquid Dispensing Machines, of which the following is a SPGCl-l fication. v

This invention relates to' new and useful improvements in a liquid dispensing machine.

One object of the invention is to provide a machine of the character described where- 7. Within the lower compartment there tion, and

byliquid drinks may tomers.

Another object of the invention is to provide a machine of the character described which will accommodate several different customers at the same time.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operaarrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings wherein Figure 1 shows a transverse sectional view taken on the line 1, 5

1 of Fig. 2.

Fig. 2 is a side elevation shown partially in section.

Fig. 3 is an enlarged fragmentary sectional view of the valve employed showing the connecting parts.

Fig. 4 is a transverse sectional view of a coin box,

Fig. 5'is an inside view of the door of the coin box showing -the locking mechanism and Fig. 6 is an edge view of said door.

. Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures the numeral 1 refers to the casing which has an outerand an inner wall, said walls being spaced apart to form the space 2 and the walls having a common top and bottom 3 and t. The chamber inclosed by said casing is separated by a transverse partition 5 into upper and lower compartments 6 and a tank 8 provided to contain carbonated water and inthe upper compartment there is a transverse cylindrical drum 9. The tank 8 is'connected to the drum 9 by means of a conduit 10 which is controlled by the valve 11. Arranged in the upper co mpart- .ment are a plurality of valve casings 12 in i Specification of Letters Patent.

1 turned and the valves operated.

be dispensed to cusouter wall of the casing is supported are fitted the tapering rotatable hollow valves 18. These valves are fixed to the inner ends of' the operating rods 14. These rods have bearings in the casing walls and theirouter ends carry the hand grips 15 by means of which the may be luid' conduit pipes 16 lead from the drum 9 to each valve casing and are provided to carry the carbonated water or other liquid to the hollow valves 13. Each of said valves has an inlet port 17 arranged to be brought into and out of registration with the corresponding pipe 16. A coil spring 18 surrounds each rod 14:, one end of said spring being secured to the 1 and the other end thereof being attached to said rod 1 1 and the tension of this spring normally holds the port 17 in registration with the pipe 16,

, valve casing there is a container 19, provided to contain syrup which forms one of the ingredients of the drink and leading down from each container, there is a pipe 20 whose lower end is fitted through the corresponding valve casing. Each valve 13 has a cup like receptacle 21 formed in the side thereo'f which is normally held in alinement under the pipe 20 by means of the spring 18, said receptacle being provided to contain the reuired amount of syrup for one drink. hen a coin is placed in one of the coin chutes 22 and the corresponding rod 14 then given a half turn, the port 17 will be carried around into registration with the outlet pipe 23 and the receptacle 21 will at the same time be carried into registration with the outlet pipe 24. These outlet pipes lead Patented Oc't. 19, 1920.

out from the bottom of the valve casing and unite in a common discharge pipe 25 casing and whose outer end carries a (1131 charge faucet 26 through which the drink is discharged into the drinking cup 27 which upon the bracket 28. When the valve is turned into discharging position the syrup will be discharged out through the pipe 24 and carbonated water will be discharged, under pressure, through the pipe 23 and these will be thoroughly mixed together in the discharge pipe 25. The rod 14 .will now be released and the spring 18 will reverse the'valve '13 and carry the port 17 and rec eptacle- 21 into registration with the respective pipes 16 and 20 and the valve 13 will thereby be filled with carbonated water and the receptacle 21 will be filled with syrup preg aratory to dis charging another drink. he pipe 25 has a valve 29 which prevents the inlet of air into the valve 13 after discharge of the drink. Coin boxes 30 are mounted on suitable brackets as 31 between the walls of the casing, a coin box being provided for each dispensing valve. Above each coin box there is a coin slot 32 cut through the outer wall of the casing and the coin chute 22 leads from this slot and enters said coin box. e coin box and locking mechanism will now be described A door 33 ishinged to said box and is formed of relatively thick material and has the vertical groove 34 in its inner face and s provided with a lining 35 formed of sheet metal. This lining has a vertical slot 36 :ut'therethrough opposite the groove 34.

On one side of the slot 36 there is secured to the plate a flange 37 which converges downwardly toward said slot and whose free edge is spaced from the plate and on the opposite side of the slot 36. there is a corresponding flange 38 which is pivoted to .the lining 35 at its lower end and normally the receiver held in vertical position by means of the flat spring which operates against the outer side thereof. The inner edge of this flange is spaced from the lining 35 and said flanges are spaced apart thus forming in effect, a coin receiver. When the door is closed the coin receiver alines under the coin chute 22 so that the coin inserted will drop down from the chute into the receiver and as converges downwardly the coin will Wedge between the flanges thereof and will be stopped. Fixed to the shaft 14 within the coin box there is a finger 40, which is arranged opposite the slot 36 and which is provided to play through said slot when the shaft 14 is turned. When the coin is inserted in the receiver the grip 15 is grasped and turned, causing the finger 40 to engage above said coin and force the same downwardly gradually, forcing the flange 38 backwardly into the position indicated in dotted lines in Fig. 5. This flange 38 carries an upwardly beveled extension 41 which normally projects across the slot 36, so that if the shaft be turned, without placing a coin in the receiver, the finger 40 will engage against said extension 41 and lock the shaft 14 against rotation, but when the coin is placed in the receiver and the same is forced downwardly tension will be carried back by the flange 38 clearing the slot 36 and permitting the finger 40 to pass and the coin is thereby forced on down out of the receiver and drops into the the finger 40 by the finger 40 the exbottomlofthe box and at the same time the valve will be turned into discharging position. When released the spring 18 will return the shaft to its original position. back of the box has a stop 42 against which engages to prevent the shaft from being rotated backwardly. Mounted upon the casing there is a cup rack 43 provided to contain cups for use of customers and which rack is provided with a door 44 which is hinged thereto and throughwhich access may be gained to said rack.

What I claim is:

1. A liquid dispensing machine including a drum, a valve casing, a supply conduit leading from the drum and entering s id casing, a container arranged above the asing, a supply conduit leading from said container and entering the casing, a hollow valve rotatable within the casing and providedwith a port, a receptacle carried by said valve, outlet conduits leading from the casing, said port and'receptacle being arranged to register alternatively with said supply and outlet conduits respectively as the valve is rotated.

2. A liquid dispensing machine including a casing, a drum therein,-a valve casing, a liquid container,v supply conduits leading from said drum and container respectively and entering the valve casing, outlet conduits leading from the valve casing, a rotatable hollow valve in said valve casing provided with a port, a receptacle contained within said valve, said port and receptacle being so located as to be brought alternatively into and out of registration with the corresponding supply and outlet conduits,

respectively, as the valve is rotated.

3. A. liquid dispensing machine including a casing, a drum therein, a valve casing, a liquid container, supply conduitsleading from the drum and container, respectively and entering the valve casing, outlet conduits leading from said valve casing and uniting in a common discharge pipe, a valve CARLTON N.
